The Vibrational Method for Studying Acoustooptic Interaction at Infralow Frequencies

In this paper, the processes of acoustooptic interaction at infralow frequencies are studied usingseismic vibrators as sources of low-frequency acoustic oscillations propagating in the atmosphere and laser measurement lines as optical receivers of oscillations. The source and receiver types being proposed to investigate the acoustooptic interaction determine the novelty and originality of the approach. The results of experiments for estimating the characteristics of the acoustooptic interactionat infralow frequencies are presented.
